Implicit_Eq_Constraint 

You can use symbolic variables to constrain geometry with an implicit equation. Lines, line segments, polygon sides, vectors and circles and conics can all be constrained with implicit equations.

  1. Select ebd_Ebd121  the geometry.
  2. Click the Implicit Equation icon ebd_Ebd122  from the Constrain toolbox, or select Implicit Equation from the Constrain menu.

An input window will open next to the geometry you selected. Highlighted in the window is a generic equation for the selected object; for a line, an equation like - XA1+YB1+C1 = 0 might appear. You can edit the equation with different variable names or coefficients as you like. You will find these variables added to the variable list in the Variables toolbox.
